The Study Of Gas Hydrate's Exploitation By Depressurization In Permafrost

Compositions, structures, properties, formation conditions, distribution feathers and gas hydrate resources as well as several detection techniques for marine gas hydrate are discussed concisely. The present situation and research tendency of experimental simulated study on gas hydrate is also introduced.This article has carried on the literature summary in view of the gas hydrate research present situation. Simply introduces its research situation domestic and foreign, then introduces his some basic identity foundation. The influence that different temperature and pressure make to the formation and decomposition of natural gas hydrate is researched. Sub sequently, the decongestive extracting mechanism of hydrate gas pool, the influence parameter and the decongestive extracting technology principle as well as the characteristic rule that natural gas hydrate obeys when it decomposes into moisture two-dimension transfusion are studied, also studied pore pressure, pressure and their influences to the rules above. through analysis, finally mechanic model of inflammable ice is established.
